What is 2/2 of 79?

How to calculate 2/2 of 79?

1. Multiply the whole number by the numerator of the fraction: 79 × 2 = 158
2. Divide this result by denominator of the fraction: 158/2 = 79
3. Simplify by dividing both the numerator and denominator by their GCD (2):
   • 158/2 = 79
   • 2/2 = 1
4. Which gives: 79/1

How does it work?

The principle behind finding a fraction of a number, such as 2/2 of 79, is rooted in the method of cross-multiplication.

Consider the following proportion: $\frac{2}{2}=\frac{x}{79}$ (where x represents 2/2 of 79)

1. Using the cross-multiplication method, multiply both numerators by their opposite denominators: $2\times 79=2x$
2. Which gives: $158=2x$
3. Divide both sides by 2 to isolate x: $\frac{158}{2}=\frac{2x}{2}$
4. Which gives the result: $\frac{158}{2}=x$ (or $\frac{79}{1}=x$)

Thus, 2/2 of 79 is equal to 79/1 (or 79 in its decimal form).
